The right time to Increase De Beers stake: Botswana’s mines minister
Botswana’s mines minister Bogolo Kenewendo says it’s “absolutely” the right time to discuss the government increasing its 15 per cent stake in De Beers.
She indicated that Anglo American, which owns the other 85 per cent of De Beers, was moving closer to an initial public offering (IPO) and that Botswana was pushing for a larger stake.
Anglo announced last week that it was likely to write down the value of De Beers from its current $7.6bn, as a result of persistent weak diamond demand, especially in China.
Botswana’s diamond, which accounts for over 70 per cent of the country’s export earnings, has been severely hit by the global slump in demand.
In the last nine months of 2024 Debswana – its 50/50 joint venture with De Beers it sold $1.53bn of rough, down 52 per cent on the same period in 2023.

De Beers Group Science & Technology Showcases SynthDetect 2: The World’s Most Versatile Automated Diamond Screening Instrument
SynthDetect™ 2 Delivers Faster Screening, Greater Automation and Enhanced Reporting For Diamond Trade Participants.
SynthDetect™ 2 builds on the leading-edge technical capabilities of its forerunners, adding greater automation, more effective reporting and faster throughput.
Collaborative approach to development means the instrument integrates effectively with diamond companies’ operations.
De Beers Group’s Science & Technology division today revealed SynthDetect 2, the next generation desktop diamond screening instrument. The first SynthDetect instrument and its successor SynthDetect XL– released in 2017 and 2018 respectively – have been among the most successful instruments in De Beers Group’s suite of diamond verification instruments due to their outstanding technical screening functionality and ability to test multiple stones in set jewellery at once without the need for a probe.
With SynthDetect 2, De Beers Group Science & Technology has worked closely with a range of trade participants to innovate on how best to integrate the technology with customer operations. This process has resulted in the development of an instrument that makes the diamond screening process significantly easier, faster and more cost-effective for diamond manufacturers, laboratories, and retailers’ back-office operations.
SynthDetect 2’s increased screening speed, throughput and productivity mean that the time taken for a full tray scan has been reduced from around 30 minutes to under five minutes. The instrument can screen more types of diamonds and jewellery than previous versions, while increased automation reduces the need for operator input, helping to reduce costs in the screening process.
With the instrument also offering automatically generated reporting and software updates, SynthDetect 2 provides a comprehensive screening tool for trade participants.
Sarandos Gouvelis, Senior Vice President for Science & Technology at De Beers Group, said:

“We have worked closely with industry partners to ensure that SynthDetect 2 is not only tailored to meet diamond companies’ screening requirements, but also to meet their operational needs. Through this process of collaboration we are proud to introduce SynthDetect 2, providing the trade with an instrument that will integrate seamlessly into their operations, marrying outstanding technical performance with enhanced speed, cost and efficiency.”
